ZXHQ-C Transformer Calibrator
ZXHQ-C transformer calibrator is a new kind of automatic testing instrument. It uses electronic technology to directly decompose the error signal of the transformer, and after proper calculation, the percentage point, in-phase error and orthogonal error of the transformer are displayed in digital quantity at the same time. The instrument has the advantages of simple operation, direct reading, rapid measurement, low power consumption and labor intensity, small volume, light weight, easy carrying and field test, and can be tested under 5% rated working current (voltage).
